' msrnnsme-mncnmn To all whom it may concern:

Be it known that I, SIGVORT HANSON, a

citizen 'of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Dispensing- Machines, of which the following is a speci-' 'fication.

' My invention relates to .a machine for under the discharge chute.

A further object is to provide a madispensing materials inmeasured quantities,

particularly for dispensing pulverulent ma terial,'such as malted milk powder,-for example, which is hygroscopic and somewhat 'stickyin itscharacter.

One of the objects of the invention is to provide in a machine of'this type a novel mechanism for positively ejecting material from the'part of the machine which receives the measured charge from the storage vessel, such positive ejection being necessary in the handling of material like malted milk powder which is likely to stick, clog or cake.

In the preferred form of my invention the ejection of the material is accomplished by a hinged, spring pressed bottom having an angular movement in the measuring pocket.

A further object of the invention is to provide a mechanism by means of which the angular position which the hinged bottom assumes when the pocket is in filling position may be varied so as to vary'the amount of the material dispensed one operation thereof.

A- further" object is to provide in a machine of this character a valve for closing the bottomof the discharge chute which is by the machine at opened by the glass, or other vessel, in-.

tended to receive material from the machine chine in which the operative parts may be readily removed in order that they may be cleaned.

The invention has for further objects such other new and improved constructions, ar-

' rangements and devices relating to dispensing machines as will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in the accompanying drawings wherein-' Figure 1 is a longitudinal sectional view taken on line l l of Fig. 2 with certain Specification of Letters Patent. Application filed August 27, 1915. Serial No. 47,611.

Fig. 2 is a sectional plan taken on line 22 of Fig. 1. Fig. 3 is a fragmentary,'longitudinal, sectional view on line 3-3 of Fig. 1. Figs. 4 and 5 are detail views, in elevation, of the discharge chute with the front plate removed but with the parts attached to the front plate shown in broken lines to show the revoluble measuring drum and the mechanism for adjusting the position and "effecting the movements of the hinged "bottom; F 1g. 4 showing the parts 'in the position which they assume just before the measuring element reaches the filling position, and Fig. 5, the position of the parts during the discharge of the material. Fig. 6 is a view, in perspective, of the inside of the front or cover plate, and Fig. 7isa similarview of the sector rack forming part of the mechanism for effecting the movements of.

' the hinged bottom.

Like characters of reference designate like parts in the several figures of the drawings. Referring to'the drawings, 10 is a table supported on a base 11. by legs 12. On the table 10 is a storage receptacle consisting preferably of a bottom plate 13, a glass cyl- .inder 14 and a top plate 15 having a filling opening closed bya cover 16. The bottom plate has an opening 17 therein registering with an openinglS in the'table. The bot-' slide 20 adapted to close the opening 17. The under side of the table 10 is formed with an undercut slideway adapted to receiveeafl dovetailed slide 21 formed on the upper end of the discharge chute'22. The latter contains a revoluble drum onmeasuring element 23 having a hub 24cextending through a boss 25 on the rear wall of the chute. The front of the chute is closed by a cover plate 26 (Fig. 6). The measuring element 23 is formed with-a pocket 27 adapted to tom plate 13 is formed with a slot 19 for a receive'material from the storage receptacle through openings 17 and. 18. ,g When the measuring element is. inverted the measured quantity of material inthe pocket is discharged.

igThefmeasurlng. element revolved by any suitable mechanism. In the preferred em,-

bodiment of the invention shown in the drawings, 28 is a shaft supported on one end by a bracket 29. The other extremity of the shaft projects into an opening in the hub 24 of the measuring element and is provided with a stud 31 adapted to engage the hub 24. A bevel gee-r32, rigidly connected with shaft 28, is meshed by a bevel gear 33 'on'a shaft 34 provided with a, handle 35 and supported in brackets 36, 36 on'the under side of the table. I Within the storage receptacle is a finger 37 attached to a shaft '38 which extends throughthe bottom plate of 1 the receptacle and through the table and is r 43 which are suspended from the under side provided on its lower end with a bevel gear,

39'meshing with a bevel gear, 40 on shaft 28.

The lower end of the discharge chute 22 is normally closed by a valve 41 supported on a cross piece 42 connecting apair of arms of the table by means of pins 44,- the upper ends of the arms extending into slots 45 in.

the table. The lower extremities of the arms 43 are connected by a cross piece 46 against which. the glass 47, or other vessel intended to receive material from the machine, is

discharge chute. In this Way the valve is moved to its open position, as indicated in f the dotted lines, Fig. *3, and forms a guide through the front wall of the measuring element, is a sector rack '51. The sector rack is engaged by a dog 52 mounted on a stud 53 ounce. The dog 52 is held in engagement with the sector rack by a leaf spring 62.

The dog carries on its outer end an antifriction roller 63 which is adapted to engage with a cam 64 formed on the inside of the cover plate 26. This engagement takes place justbefore the measuring element has been turned'far enough to completely invert the pocket. The dog is thereby rocked so as to be freedfrom the sector rack. Av coiled spring 65, of proper length interposed between the inner wall of the pocket and the hinged bottom, 49, and having frictional en gagement with studs on these members forces pushed when the glass is placed under the on the front face of the'measuring element 23. The sector rack carries on its outer face an anti-friction roller 54 adapted to meet a contact member 55 which is pivotedat 56 to the inside of the cover plate 26 and at the other end is connected by a link 57 to an arm 58. The arm 58 is rigidly connected to a short shaft 59 which is revolubly mounted in the cover plate 26, and carries on its outer end a pointer 60. .The roller 54 comes against ,the contact member 55 just before the op ning in the measuring element registers ith the-openings 17, 18. The further rotation of the measuring element rocks the sector rack 'thereby depressing the hinged bottom 49. The amount of movement thus imparted to the hinged bottom is determined by the angular position of the contact member 55. The position of the bottom, of

course, fixes the volumetric capacity of the measuring pocket. The contact member 55 is set by movlng the pointer 60. Preferably the cover plate 26 is provided with 'a sca'le61 graduated, for example-for fractions of an pocket.

the bottom outwardly .of the pocket as soon as the dog 52 releases the sector rack 51.

This movement'of the hinged bottom effects a forcible and positive ejectment. of'the vmaterial in the pocket. Because of its-angular movement during the ejecting operation, the

bottom is much less likely to become clogged than if it were moved. bodily forward and back as a plunger. The lengthof the spring 65 and its frictional engagement with the studs on the hinged bottom and the inner wall of the pocket limits the outward movement 'so as to prevent it from being forced beyond the outer edge of the opening of-the It will be understood that slide 20 is ordinarily kept open. Whenit is found necessary to clean out the measuring and ejecting mechanism the-slide 20 is closed, the set screw 48 loosenedf'and the chute 22 removed.

The loose or detachable connection of shaft '28 with the hub 24 of the measuring drum 23 The measuring drum makes this possible. may .be taken from the chute by removing the cover plate 26 from the latter.

The operation of the machine. above de scribed is as followsi'The attendant takes a glass 47 and slides it backwardly across the base plate against the cross piece 46.- This moves the valve-41 to its open posi-' tion in which position it forms a deflecting plate for guiding the material from the chute into the glass. The attendant gives the handle 35 'a complete revolution. The

pocket in the measuring drum is brought into register with the openings 17, 18 and the bottom 49 is depressed by contact of the roller 54 on the sector rack with contact member 55.-

the adjustment of the contact member 55 effected by means of pointer 60 on the scale 61. Thebody of material in the receptacle is broken up by the revolving finger 37 which, operating over openings 17, 18, sweeps the materialinto the pocket, insur- The amount-that the bottom is rocked or depressed will depend upon ing the filling of the pocket in case the supply in the receptacle should below. When the measuring drum reaches its inverted position the roller 63 on dog 52 comes into contact with cam 64, causing between member i and roller 54.

. the dog to release the sector rack 51. The

spring-65thereupon forcesthe hinged bottom downWardly,;,r ejecting the material through the chute into the glass 47..

' It will be seen that the pointer constitutes the manually operated setting member of a quantitvsetting device. When a discharge of materialinto the tumbler 47 is desired, the amount to be discharged "is indicated by moving the pointer 60- to the proper graduation 61. Considering the parts as in the position shown in Figs. 1

and 4, let it be assumed that the operator desires a larger discharge 'of material. To

accomplish this he moves the pointer 60 to the left, as viewed in these figures. This moves member 55 about its pivot 56. toward the axis of the revoluble measuring element 23, thereby moving the sectorrack 51 downwardly about pivot 50 because of conjiact he downward movement of the sector rack causes a downward movement of the hinged bottom 49 of the measuring element, this downward movement occurring as the handle 35 is turned subsequent to the setting of the pointer 60. VYhen the bottom 49 has reached its inward limit of movement, as determined by the'position of member 55, the dog, 52 will engage with that tooth of the sector rack 51 which is adjacent it, and will hold the bottom in that lowest position. The parts will .remain in this relative position during rotation of the meas-v uring element until roller 63 engages cam 64; This engagement will throw dog 52 out of engagement with the sector rack, allowing spring .65 to expand and throw bottom 49 outwardly, thus forcing the material in the measuring element outwardly toward the now invented opening of the measuring element. This movement of the bottom forces the hygroscopic material out of the measuring element into the tumbler 47 or other receptacle provided. Consider ing the parts as positioned in Figs. 1' and 4 again, it is obvious that a movement of the pointer 60 to thezright will move member 55 clockwise about its pivot 56 and reduce the distance of inward travel of bottom 49 as the measuring element is rotated, thereby reducing the amount of material which the measuring element will receive and subsequently discharge. After disengagement of the dog 52 from the sector rack by contact between roller63 and cam 64, the' bottom is again set in any desired position, first, by predetermining, the

amount desired to be discharged through movement of the pointer 60, and then by manipulation of crank 35, which results in rotation of the measuring element until roller 54 has engaged member 55 and forced the bottom down as far as the position of member 55 determines.-

While I have described my invention in a preferred embodiment, it will be understood that modifications might be made without departing from'the principles of the invention. Therefore I do not wish to be considered as limiting the invention to the particular constructions, arrangements and devices shown and described'except so far as the claims hereto appended are expressly so limited.
